4 Things that could help reduce risk of Prostate Cancer

Researchers at the University of Alabama at Birmingham (UAB) came to the conclusion after a study of male mice that were fed a plant compound found in red wine called resveratrol. The findings were published Saturday in the online edition of Carcinogenesis. (Source: China)

The nutrients in red wine have shown anti-oxidant and anti-cancer properties. Other sources of resveratrol in the diet include grapes, raspberries, peanuts and blueberries.

In the study resveratrol-fed mice showed an 87 percent reduction in their risk of developing prostate tumors that contained the worst kind of cancer-staging diagnosis. The mice that proved to have the highest cancer-protection effect earned it after seven months of consuming resveratrol in a powdered formula mixed with their food.

Other mice in the study, those fed resveratrol but still developed a less-serious form of prostate cancer, were 48 percent more likely to have their tumor growth halted or slowed when compared to mice who did not consume the compound, according to the study.

This study adds to a growing body of evidence that resveratrol consumption through red wine has powerful chemoprevention properties, in addition to its apparent heart-health benefits, said lead study author Coral Lamartiniere, Ph.D., of UAB’s Department of Pharmacology and Toxicology.

Reduced Risk Prostate Cancer with Regular Ejaculation

An epidemiological study of 30,000 American men by Michael Leitzman, a cancer researcher at the National Cancer Institute in Bethesda, Maryland, has found that men who enjoy an active sex life do not risk prostate cancer in later life.

There has been a suggested link with greater sexual activity and increased incidents of prostate cancer in previous scientific data because of the link with the male hormone testosterone and its effect on promoting cancer cell growth.

Leitzmann’s findings were that men who ejaculate between 13 and 20 times a month had a 14% lower risk of prostate cancer that men who ejaculated on average, between 4 and 7 times a month for most of their adult life.

Men who ejaculated upwards of 21 times a month had a 33% lower lifetime risk of prostate cancer than the baseline group. (Source: About)

Veggies could help reduce risk of prostate cancer

New evidence indicates that the risk of prostate cancer may be reduced by adding certain vegetables to one’s diet. (Source: Go)

Researchers at Yale School of Medicine found that men who ate broccoli, cauliflower, cabbage, brussel sprouts, and turnips were 40 percent less likely to be diagnosed with aggressive prostate cancer, compared to those whose ate those vegetables less than once a month.

Men who ate cauliflower more than once a week were 52 percent less likely to be diagnosed with prostate cancer, and men who ate broccoli more than once a week were 45 percent less likely to be diagnosed with the disease.

The study is reported in the Journal of the National Cancer Institute.

Fatty fish consumption slashes risk of prostate cancer by 43 percent

Men who eat just one serving of salmon per week reduce their risk of developing prostate cancer by 43 percent, compared to men who do not consume fish, according to new research published in the online edition of the International Journal of Cancer.

Researchers from the Karolinska Institute in Stockholm examined the dietary habits of nearly 1,500 men with prostate cancer and more than 1,100 men without the disease. They found that men who ate fatty fish rich in omega-3 fatty acids, such as salmon, at least once a week reduced their risk of prostate cancer by 43 percent, whereas men who did not eat fish of any kind experienced no risk reduction.

The researchers — led by Maria Hedelin — also believe that a certain gene may play an important role in the development of prostate cancer, as well as how fish oils benefit the body. A specific Cox-2 gene that is present in 60 percent of the population can influence the effectiveness of omega-3 fatty acid consumption, the researchers reported.

Men who carry the gene have a 72 percent reduced risk of prostate cancer compared to those who do not carry it, but eating fish high in omega-3 fatty acids can still benefit men who do not carry the gene, according to the researchers. (Source: NewsTarget)
